Abstract
We shall deal with the problem of renormnalization of Bethe-Salpeter equations in the ladder approximation in the light-front quantum electrodynamics (QED) and quantum chromodynamics (QCD) for several non covariant gauges. The Bethe-Salpeter equation in the light-front, for the bound state of two fermions exchanging gauge bosons, presents in the ladder approximation, divergences associate…
